has anyone had problems with the servo screws coming out of this servo. i had a terrible crash the other day due to this very occurence. the odd thing was one of the servo horns was laying about a foot from the crash unscathed.brand new 9155 with the servo screw lockited with 243 loctite. the machine is smooth as siilk and was crusing around nicely in foward flight when all of the sudden it rolled left into the gound, no saving it. it just make me sick, i have been flying this machine with jr 8611a's for 1.5 years now with no incident, changed to the futba servos( just to try something different) and was not even able to get thourgh 1 flight. i never had to locktite my jr servos and they come with a lockwasher unlike the futaba servos. frankly im pissed 800 in damages including the pipe and canopy. just wondering how many others have expereanced anything like this.

talked to futaba and of course they have never heard of this happening to anyone. guess from now on I'll have to use a small amount of red lockite and a lockwasher just to be on the safe side.

do you mean 9255

If you mean 9255 I have about 12 of them and have never had a prob. Were you using metal servo horns? On my 9255's I use a small dab of blue loctite after I clean the screw with a little bit of alchol...

Sorry to hear about your loss!!!

no, i had the Black futaba round wheels. i think the 9155 might have the same spline gear as the 9255 but it is an updated version of the 9351

I have the 9255 had the same situation. lost collective end result
crash and burn. screw was missing used loc-tight
found out the screws that come with the servos are smaller when
mic test was done. if you use a hex head bolt 2mm they are on the money trust me the o.e.m. screws on 9255 9155 will come off
causing crash
